A dramatic history of Pu Yi, the last of the Emperors of China, from his lofty birth and brief reign in the Forbidden City, the object of worship by half a billion people; through his abdication, his decline and dissolute lifestyle; his exploitation by the invading Japanese, and finally to his obscure existence as just another peasant worker in the People's Republic.

Two neighbors form a strong bond after both suspect extramarital activities of their spouses. However, they agree to keep their bond platonic so as not to commit similar wrongs.

Based on the real life story of legendary cryptanalyst Alan Turing, the film portrays the nail-biting race against time by Turing and his brilliant team of code-breakers at Britain's top-secret Government Code and Cypher School at Bletchley Park, during the darkest days of World War II.
